Stability of limonin from lime seeds

Limonin was isolated and purified from lemon seeds. The effects of temperature and pH on stability of limonin were studied. Limonin had a reaction rate of an apparent first order type. It was most stable in pH 5 at 45°C.The solid limonin had a first order reaction of decomposition with the reaction rate constant of 1.58x10 - 3 day - 1 at 45°C.
